page.get_links() is not returning all links

[1504168]

I am trying to extract links from this particular PDF file(attached). But when I use page.get_links() it shows an empty list. I don't understand why.
Especially on the 2nd page, I can see multiple links.

Here is the sample code:

import pymupdf
doc = pymupdf.open('faster_rcnn.pdf')
page = doc[1]
print(page.get_links())

faster_rcnn.pdf

The page indeed contains no links!
There exists text that looks like a link, but this is just text.
PDF viewers usually still react to this type of text format as if a link had been technically defined. This causes your confusion.

Okay. It seems so. I think that I will need to use regex and get_text option.
